Title: Method and apparatus for inserting a flexible membrane into an eye
Inventor: HEYMAN THOMAS M
IPC: A61F2/16
Filed: 1997-09-25
Granted: 2003-04-01
Abstract: This invention is an instrument (10) for inserting a flexible intraocular lens or other flexible membrane into an eye, which includes a compressor (26) for laterally compressing the lens into a small cross-sectional configuration to pass the lens through a narrow incision. The compressor includes retainers (68, 70) along the interior of the inserter to maintain the side edges of the lens in a substantially planar orientation during compression. The retainers preferably extend through the inserter to hold the lens during advancement toward the eye to prevent an uncontrolled rotation of the lens.

Title: Control system for internal combustion engines
Inventor: WEISS HEINZ
IPC: F02D41/24
Filed: 1999-04-29
Granted: 2002-04-16
Abstract: A control system for internal combustion engines of an agricultural tractor include a memory unit in which is stored engine performance maps. The control system includes a vehicle speed sensor and transmits control signals to an electronically controlled fuel injection system to control the fuel injection quantity as a function of sensed speed, target value inputs and as a function of the engine performance maps. The control system, in response to sensed vehicle speed, limits the maximum engine output as a function of the vehicle speed. In particular, at lower vehicle speeds the engine output is limited to a level which is lower than the rated engine output.

Abstract: A carrier reproducing circuit capable of reproducing a carrier quickly, wherein: a signal point arrangement convening circuit (14) detects the signal point arrangement of a demodulating baseband signal of a carrier when the carrier has a frequency different by a predetermined value from the center frequency of the modulated wave; a variance calculating circuit (15) calculates, based on the signal point arrangement, the number of times that the variance exceeds a preset threshold per unit time; a CN determination circuit (16) determines the reception CN ratio based on the number of times; a scanning step frequency width converting circuit (19) sets a frequency width changed by one step based on the determined reception CN ratio; the carrier for demodulation is sent out by changing oscillation frequencies of oscillators (6, 7) through an AFC circuit (20) based on the preset frequency width; and when a carrier synchronization judging circuit (18) detects that the number of times decreases to a value equal to or smaller than a threshold determined based on the reception CN ratio, the scanning by the AFC circuit (20) is stopped.

Title: Adaptive pre-equalization apparatus for correcting linear distortion of a non-ideal data transmission system
Inventor: TWITCHELL EDWIN RAY
IPC: H04B3/04
Filed: 1998-07-23
Granted: 2008-01-22
Abstract: An apparatus (10) for compensating a linear distorting action to an information signal within a transmission system (12). Within the system (12), an information signal proceeds to a transmitter (24) that has an amplifier (62). A sample signal is coupled-off from the transmitter (34). The linear distorting action of the system (12) includes shifting of at least one aspect of the signal away from its intended value. A linear pre-equalizer (54), located along a signal stream of the information signal to the transmitter (34), pre-equalizes the information signal. An adaptive equalization determination (70), connected to receive the sample signal and the information signal outside of the signal stream to the transmitter (34), determines an amount of pre-equalization required from the linear pre-equalizer (54) to compensate the linear distorting action of the system (12). The pre-equalization by the linear pre-equalizer (54) is modified in response to the determination by the adaptive equalization determination (70).

Abstract: A BS digital broadcast receiver having no 8PSK demapper and a less number of delay circuits for Trellis encoding. A QPSK baseband signal based upon a reception signal point position of an absolute-phased baseband demodulation signal is Viterbi-decoded by a Viterbi-decoder 6. An output of the Viterbi-decoder is convolution-reencoded by a convolution encoder 7. Upper four bits of phase error data are searched from a phase error table 31 for carrier reproduction in accordance with a phase difference between 0 degree and a phase of a phase error detection reception signal point position. The upper four bits are delayed by delay circuits 81 to 84 by a total sum of a time taken to Viterbi-decode and a time taken to convolution-encode. The delayed outputs are demapped by a demapped value conversion circuit 9. A code TCD2 determined from the demapped output and convolution encode output is output as an MSB of a Trellis 8PSK decode output from an MSB code judging/error detecting circuit 10.

IPC: H04Q11/04
Filed: 2001-02-14
Granted: 2005-05-24
Abstract: A heterogeneous telecommunications system employs "out of band" signalling to automatically discover the identity of the two ports connecting two network elements through a specific link. Either of the connected network elements may be a circuit switching network element or a packet switching network element. One network element initiates the port discovery process and transmits an overhead signal, such as a SONET/SDH protection switching message, to the network element attached at the other end of the link. The other network element monitors the status of its ports and, when it detects a change in state at one of the ports, resulting from the first network element's transmissions, the receiving, or passive, network element recognizes the port as the port which forms a part of the link of interest.  Each group of network elements, packet switching and circuit switching, elects a network element leader which coordinates requests for port identification.

Title: Multi-layer conduit
Inventor: SHAFIEE SAM
IPC: F16L11/12
Filed: 1999-11-15
Granted: 2005-02-08
Abstract: A conduit for use as a filler pipe for transferring hydrocarbon containing fuels such as gasoline from an inlet point to a storage tank which is to be blow molded comprises a plurality of layers. The innermost layer (12) is made from electrically conductive high density polyethylene and serves to bleed off static electricity generated during the fuel filling process. At least one of the other layers of the conduit comprises barrier material (18) which inhibits the passage of hydrocarbon vapours through the walls of said conduit as hydrocarbon containing fuels flow along the conduit. Advantageously, the conduit may include a mounting tab (30) intermediate the ends, the tab (30) having a web portion which is electrically connected to the inner conductive layer (12) to assist in locating the fuel filler conduit and providing additional conduct of static electrically to the vehicle body or frame. A process for manufacturing such multi-layer conduit comprises simultaneously extruding a multiplicity of layers through a multiple head extruder. Advantageously, a tab as desired may be formed by pinching the extruded parison after initially blowing the parison and before finally blowing the parison.
